CuIO4
CuIO4 is a thermodynamically stable, semiconducting spinel oxide material used in catalytic research.
About CuIO4
CuIO4 is a distinct member of the spinel oxide catalyst family, characterized by its semiconducting electronic nature. Its position on the thermodynamic convex hull highlights its inherent stability, making it a robust candidate for research in complex oxide systems. The material exhibits structural versatility, evidenced by multiple reported configurations across crystallographic databases. This stability and electronic profile suggest significant potential for specialized catalytic functions where precise control over charge transport is required. As a stable oxide, it serves as a valuable subject for investigating the interplay between transition metal coordination and oxygen-based frameworks in catalytic cycles.
Key Properties
Cross-validated computational properties for CuIO4, aggregated across 3 databases.
Band GapEnergy needed to move an electron from the valence band to the conduction band. Lower or zero values tend to behave more metallic; larger gaps are more insulating or semiconducting.
Energy Above HullThermodynamic distance from the most stable set of competing phases. 0 eV/atom is on the convex hull; small positive values may still be experimentally accessible.
StabilityA plain-language summary of the best reported energy-above-hull result. It reflects whether the lowest-energy structure is on, near, or far from the stability hull.

How It Compares
Within the spinel oxide catalysts class.
Within the broad class of spinel and related transition metal oxides, CuIO4 occupies a unique niche compared to more conventional binary oxides like CuO or ZnO. While simple oxides such as NiO or Al2O3 are foundational in industrial catalysis, CuIO4 offers a more complex structural arrangement that distinguishes it from the simpler cubic lattices found in MgAl2O4 or the perovskite-structured LaNiO3 and LaMnO3. Its thermodynamic stability relative to these well-known siblings positions it as a sophisticated alternative for researchers seeking to tune catalytic activity through more intricate metal-oxygen bonding environments.
